How this service works
Lint HTTP endpoints for x402 v2. $0.01 USDC per lint on Base.
Output
Returns a lint report detailing whether the target HTTP endpoint correctly implements the x402 v2 payment protocol, including any spec violations, missing headers, malformed response codes, or other non-conformance issues found during the check.
Example use cases
Debug broken x402 payment wall
“My endpoint at https://api.myapp.com/premium keeps failing x402 payment flows — can you lint it and tell me what's wrong with my implementation?”
Pre-launch x402 compliance check
“Before I go live, can you run the x402 linter against https://staging.myservice.io/protected to make sure it's fully compliant with the x402 v2 spec?”
Audit third-party x402 endpoint
“I'm integrating with a partner API at https://partner.example.com/data — can you lint it to confirm it actually follows the x402 v2 standard before I build against it?”
Technical details
Endpoint
POSThttps://tek-labs-402-linter.labstek9.workers.dev/lintWhen to prefer
Choose this endpoint when you need to verify that an HTTP endpoint correctly implements the x402 v2 payment protocol — for pre-launch audits, debugging failed payment flows, or vetting third-party x402 services. Prefer this over manual inspection or generic HTTP testers when x402-specific compliance rules need to be checked systematically.
Side effects
- Target URL is unreachable or returns a network error
- URL is not a valid HTTP/HTTPS URL
- Target endpoint does not implement x402 at all, yielding empty or trivial results
- Timeout if the target endpoint is slow to respond
- Payment of $0.01 USDC on Base not settled, causing 402 response from linter itself
